The aim of this project is to study the role that online videogames play in way people build their identities. More specifically, intended how use and virtual avatars explore alternative It possible for manifest entirely different versions themselves through characters. Sometimes, those identities may be a projection what players consider ideal themselves. Several variables strengthen or hinder...

Highly differentiated work procedures require stakeholders to share knowledge within and between communities. In the course of knowledge sharing, not only explicit knowledge has to be communicated, but also tacit knowledge. Tacit knowledge cannot be exchanged by traditional means, such as language. For externalization of tacit knowledge we currently face a lack of accurate method support. We in...

This work presents a grid-based fuzzy expert system environment, which employs a repertory grid, fuzzy theory and case-based reasoning. The proposed environment provides friendly user interfaces, abundant data types, intelligent knowledge acquisition facilities and an efficient inference engine. To help users make precise decisions, three factors (i.e., feasibility, reliability and certainty) a...

Variations exist among information system (IS) users’ abilities to effectively utilize an IS. Some users are able to maximize IS potential, while others are not. This research proposes to understand the attributes of individuals who are most capable of exploiting IS to its fullest potential as well as the management and organizational factors that facilitate the development of highly competent ...

In software visualization, but also in information visualization in general, there is a great need for evaluation of visualization metaphors. To reduce the amount of empirical studies a computational approach has been applied successfully, e.g., to graph visualization. It is based on measurable aesthetic heuristics that are used to estimate the human perception and the processing of visualizati...

Exploratory testing is neither black nor white, but rather a continuum of exploration exists. In this research we propose an approach for decision support helping practitioners to distribute time between different degrees of exploratory testing on that continuum. To make the continuum manageable, five levels have been defined: freestyle testing, high, medium and low degrees of exploration, and ...

Evaluation of social awareness is a relatively new area of research in the field of Human Computer Interaction. In this paper, a system called Panorama that supports social awareness among co-workers of a computer science department is evaluated, to see how it supports awareness and how the users experience it. Observations and interviews are used to see how users respond to the system, as well...

We present a study that explores people’s affective responses when experiencing data represented through different modalities. In particular, we are interested in investigating how data representations that address haptic/tactile and sonic perception are experienced. We describe the creation of a number of data-driven artifacts that all represent the same dataset. In taking a phenomenological a...
